SASH--FSTENEARL srEcjrr"rcermv forming part of Letters Patent No.524,146, dated August 7, 1894. Application filed April 30,1894. SerialNo. '509.5 32. (No model.)

Be it known that I, JOHN H. HOTTES, of St. Louis, Missouri,have inventedcertain new and usefulrlmprovements in Sash-Fasteners, whichimprovements are fully set forth in the following specification andillustrated in the accompanying drawings.

The object of my invention is to construct a sash fastening device, onethat is simple in construction, easily operated, and efficient in use.

A further object of my invention is to construct.a sash fastener thatwill lock the meeting cross rails ofthe upper and lower sash together,in such a firm and substantial manner that it will be:impossible to gainadmittance through the window on which myfastener is located.

, y.invention consists in a casingiuclosing a'spring actuatedishootingbolt, a looking bolt adapted to eugageagainst said shooting bolt,

and certain other new and A claimed.

novel features of .construction hereinafter described and -In order'that my. invention may be more fully understood, I will now proceed todescribe it, reference being had to the accompanying drawings,in which-Figure 1. is a perspectiveview of my complete device attached toawindo'w, as required for practical use, parts being broken improvedfastener.

away to more clearly ill'ustrate same. Fig. 2. is a" longitudinalcentralsectional view of my Fig. 3. is a perspective view of theshootingbolt'l make use of in carrying out my invention. Fig. 4. is aperspective view of the finger hold and sleeve that engages one end ofthe shooting bolt. Fig. 5. is aperspective view. of the looking bolt.Fig. 6. is a perspective viewof the base plate which is secured to thewindow sash, and to which the main casing is riveted. Fig. 7. is

a perspectiveview of the key used in connection with my improvedfastener.

' Similar numerals refer to similar parts throughout the several views.

The numeral 1 designates the base plate which is rectangular in form andhaving the two forward corners cut away, said=cutaway portions beingnumbered2 and 3. At the forward and rear ends of this plate 1, are theupwardly extending lugs, 4 and 5, which are provided with thesemicircular cutaway portions 6 and 7. Rectangular apertures 8, 9,10 and11 are formed in the plate in pairs between the lugs 4 and 5. Screw orbolt holes 12 are also formed in the plate near the outer edges thereof.r

Numeral 13 designates the main casing of my fastener, which ispreferably rectangular in cross section, and composed of the top 14,sides 15, and ends 16, said ends 16 having semi-circular cut awayportions therein to mate With the semi-circular cut away portions 6 and7 previously mentioned.

Near the ends of the casing 13 and brazed to the sides and top thereofare strips or bands 17, which extend downwardly and through theapertures 8, 9, 10 and 11, in the base plate 1, and are there securelyriveted.

By the meeting of the semi-circularcut away portions6 and 7, and the cutaway portions in theends of the main casing it will be seen thatcircular openings are formed in the ends of the main casing, throughwhich the cylindrical portion of the shooting boli: operates.

Formed integral with and extending upwardly from the central portion ofthe top 14, of the casing 13 is a circular lug -18, which is providedwith a vertical screw threaded bore 19, communicatir1g with the interiorof the casing 13-, and an annular bore 20,'slightly larger than thescrew threaded bore 19. Within this annular bore 20 and screw threadedbore 19, operates the looking bolt.

The shooting bolt I make use of, is a suitable amount longer than thecasing 13, and is composed of the main body portion 21, which isrectangular in form, and has formedintegral thereon the extendingportions 22and 23,

circular in cross section.

The rectangular body portionis provided on its upper face with a seriesof circular depressions, 24. One of-the lower corners of thisrectangular portion 21 is cut away, designated by 25, the. purpose ofwhich will be 1 presently described.

The outer end of the circular extending portion 22 is screw threaded andadapted to receive a nut 26. A sleeve 27 provided 011 its outer end witha ring 28 is located upon the portion 22 of the shooting boli: and isheld thereon by means of the nut 26. This sleeve is provided with aseries of upwardly extending lugs 29. An opening, 30, formed in the end16 of the oasing 13, allows, the passage of these lugs 29 duringmanipulation of the shooting bolt.

The looking bolt designated by the numeral 31, is formed of theperipherally sorew threaded body portion 32, which engages in the sorewthreaded bore 19, and the integral triangular portion 33 which 1ieswithin and extends through the annular bore 20. The lower point of thebody 32 is attenuated. This attenuated portion 34 is adapted to engagein the depressions 24 previously mentioned.

A key 35 oomposed of the body 36 having a triangular bore therein, anarm 37 and ring 38 provides means for manipulating the locking bolt.

A ooil spring 39 is interposed between the body portion 21 and the endportion 16 of the casing and serves to normally hold the shooting boltforward or as in the position shown in Fig. 2. A lug 40 extends upwardlyfrom the base plate 1, and engages against the out away portion 25 onthe body 21, and serves to restriot the rearward lateral movement of theshooting bolt.

By means of sorews 41 the base plate 1 carrying the oasing,- &o., issecurely held to the upper rail of the lower sash. A clip 42 is held bymeans of sorews to the lower rail of the upper sash.

The operation of my improved sash fastener is as follows: When it isdesired to look the sash together the rails oarrying the parts of thefastener are brought together so that the portion 21 of the shootingbolt, forced forward by reason of the action of. the ooil spring 39,engages beneath the clip 42. By now placing the key 35 on the triangularportion 33 of the looking bolt 31 and manipulating same, the attenuatedpoint 34 engages in one of the depressions 24, in the rectangularportion 21, of the shooting bolt, thereby fir'mly looking said shootingbolt, and thoroughly preventin g any rearward or lateral movement ofsaid shooting bolt. When it is desired to unlookthe device so as toraise or lower the window sash the looking bolt is so manipulated as tobe disengaged from the shooting bolt. By now pulling the shooting boltout by means of the ring or finger hold 28, the forward end of saidshooting bolt will necessarily become disengaged from the clip 42. Thesleeve 27 oarrying the lugs 29 which have just been drawn through theopening 30, is now given a slight turn either to the right or left and,as said sleeve is loose upon the portion 22 of the shooting bolt, andthe lugs engaging against the end 16 serves to retain the shooting boltin its Withdrawn position. The sash can now be either raised or lowered.

When it is desired to look the shooting bolt while in its normalposition and without the use of the looking bolt the sleeve 27 is turnedslightly to the right or the left. As this movement brings one of thelugs 29 into engagement with the inner side end 16, it will be,

plainly seen that the shooting bolt cannot be withdrawn until the sleeveis so turned as to bring the lugs 29 so that they register With theopening 30.

Thus will be seen how I have provided a simple, cheap, and effioientsash look and fastener, one that when locked cannot be unlooked by anyone without thekey, or cannot be tampered with by any one on the outsideof the window.

What I claim is 1. A sash fastener oomprising a rectangular base plate,a rectangular three sided casing riveted to said plate, a springaotuated shooting bolt having a rectangular body portion provided with aseries of -depressions, a sleeve loosely mounted upon one end of saidshooting bolt and provided with a series of lugs, and a vertical lookingbolt operating in the oasing all substantially as described and for thepurposes started.

2. A sash fastener oomprising a reotangur lar casing,a spring aotuatedshooting bolt looated within said casing, a sleeve loosely mounted uponsaid shooting bolt, said sleeve being provided with a series of lugs,and a lookingbolt, oomprising a triangular portion adapted to be engagedby a key, and a peripherally sorew threaded body portion having anattenuated point, all substantially as shown and specified.

3. In a sash fastener a spring aotuated shooting bolt operating within aoasing comprising a rectangular body portion, which is provided with aseries of depressions, and extending circular portions, and a sleeveprovided with a series of lugs and a finger hole or ring, looselymounted upon one of the circular portions of the shooting bolt,substantially as shown and specified.

4. In a sash fastener a looking bolt placed vertioally within anextending lug on the oasing, oomprising a triangular portion, and aperipherally sorew threaded body portion, which has its lower endattenuated, to operate in the manner set forth and for the purposesstated. 4

In testimony whereof I affix my signature in presence of two witnesses.
